LOL! Sorry (not really) to be a party pooper, but are we supposed to cheer for #SpaceX each and every time they test a rocket? Whether it explodes on the launch pad, in mid-air, upon re-entry or upon landing? Have we done so with other tests? Like with NASA's tests, which are paid for directly by the taxpayer?

No, we haven't. So then, wake me up when the tests are done with and a usable rocket can fly and transport cargo and people safely to somewhere.

That's how success will be measured.

New blog post: Decoding ERMINAZ. Here I speak about the comms of the upcoming AMSAT-DL ERMINAZ satellites, for which I've recently added support to gr-satellites. These use the OSDLP stack from Libre Space Foundation QUBIK and will transmit SSDV images. https://destevez.net/2024/06/decoding-erminaz/

That was fast! After a couple of days of taking samples and taking selfies, China's Chang'e-6 probe lifted off from the moon's far side and is due to rendezvous with an orbiter to stash those samples for the trip back to Earth. https://cosmiclog.com/2024/06/04/chinese-probe-collects-moon-samples-and-lifts-off/ #Space #ChangE6 #China #Moon

While in the current political discussion climate this theme is easy to forget, the current @EUCommission has been pursuing a very privacy-hostile #ChatControl policy for digital communications, which the current EU Parliament has opposed. As you pick your candidate for #EU2024 elections, pay attention to their track record on digital, consumer, privacy questions. This matter is not settled yet, nor will it be the last such matter.

A very greyish Phobos the potato shape satellite orbiting over the rusty red planet, some craters are also visible on both Mars and Phobos.
Valles Marineris, the most famous gran canyon on Mars, its length is comparable to the width of the United States - surface is rusty red as you would expect on the red planet - some whitish faint clouds.
An orbital image of Mars showing off its 5 volcanoes and its little potato shape satellite Phobos. Surface is rusty red and cloudy especially at the poles.

This is a decent summary of the octopus thought experiment from Bender & Koller 2020, with two glaring exceptions, right at the start:

1. We were NOT talking about "AI". That's a paper about language models, and even though other people are (now) talking about LLMs as if they were AI, we weren't and never would.

Here is a 'finder chart' (a term borrowed from astronomy. Don't tell anyone) for the Chang'e 6 landing site. #maps

Mapky s místem přistání čínské sondy Chang'e 6. Mapky jsou v ortografické projekci se středem projekce v místě přistání (41.64°S, 153.99°W).

Mapku jsem aktualizoval s přesnějšími souřadnicemi místa přistání. Podle UMSF jsou jeho souřadnice 153.98545 W, 41.63839 S, ale zatím nejsou oficiální.

Departing from the current theme today: it appears the Chang'e 6 landing has been successful, so here is an updated lunar sites map:

Soon the telescope platform at ESO's Paranal Observatory in #Chile will look very different at night: all four of the 8.2 m telescopes of the VLT will be equipped with lasers! This is one of the ongoing upgrades of the GRAVITY+ instrument, which will allow us to study black holes, stars and planets like never before.

Zooming in on a peculiar white rock in Neretva Vallis

This is a combination of three SuperCam RMI images and one Mastcam-Z image taken by the #Perseverance mars rover.
The images were taken two days ago on Sol 1164.

I felt a bit experimental and concept-driven with this #watercolor painting last night, I'm happy with the outcome. I just wish I had access to the rest of my art supplies. Most of them are still in boxes since our move, because we have no space for them yet in our new home. So I'm stuck with the same Daler Rowney paints since last September.

And this map shows the radius in kilometers as it varies over the nucleus. Read the paper here:

https://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1991A%26A...248..656S&defaultprint=YES&filetype=.pdf

(let me know if the link doesn't work).

Unfortunately for us, it's all hogwash! This paper:

Belton, M.J. et al., 1991. The spin state and homogeneity of Comet Halley's nucleus. Icarus, 93(2), pp.183-193. https://doi.org/10.1016/0019-1035(91)90207-A

gives a different rotation state, so the images show different parts of the nucleus than we expected, and Halley has long axis rotation. #maps

That white-ish rock (https://mastodon.social/@65dBnoise/112527256691375965) has quite an interesting texture. Seen here with #Perseverance's telescope.

Drystone today in a rather lush garden. Working on a retaining wall built from Yorkshire sandstone. Building on a curve with really straight edged stone is always a challenge. As is my mosquito/midge allergy during Scottish summers.

The basic principle of a retaining wall is that the wall's depth should be roughly the same as its height. So a 1m high wall extends back 1m into whatever it is retaining.
